Uh, yea, Rhett is absolutely right. Don't expect 40+ fps running a complex add-on with FSX. With your setup you can expect about 60fps with the default flight and settings (as per benchmark from arstechnica.com on a similar CPU/GPU combination), but expect your frame rate decrease by about 20-30% with a glass cockpit from the default planes and maybe cut in half with with a complex add-on. Add to it that you're running everything maxed (traffic?) and I wouldn't be surprised about the 7fps.Try again with slider in a "Medium-High" setting, maybe some fsx.cfg tweaks and less AA/AF and I am sure you will easily hit 20 fps - which would be an absolute dream for me.Pat

I have the same mobo, I'm certain that it only supports up to PC26400 DDR2. Could be something to do with that!

i have just built this very high spec machine hoping for smooth frames in fsx but have been sorely dissapointed as have achieved as low as 7 fps in built up areas with the queen and all sliders maxed out. I realy thought my performance problems would be over with this lamborghini of computers. I have installed all the latest drivers and enabled sli and every possible tweak yet fsx still kills it even though my 3d mark score of 61512 is pretty high.

Did the wife say goodbye when she left? lol :-)

two things. if you want a little bit more fps overclock your machine. second for those of you who think that no pc can max fsx well you are wrong. irun fsx maxed at 35fps

no not a word , when i landed there was no sign of her anywhere , admitedly it had been a 21 hour flight with stop over, well i i had offered her a jump seat ticket but she declined so what can you do :) most unreasonablekav

5.7GHz on a $3000 cooler? I was about to ask whether perhaps your vacuum cleaner can pull the moon into closer orbit with the earth?But then I saw this (>4.6GHz with air cooling):http://flyd.net/visit.asp?fldid=448233These results are very startling (barely credible, frankly) compared with Intel's own experiments. See this: http://www.tgdaily.com/content/view/34636/135/But if true, then perhaps significantly higher clockspeeds for the mainstream are nearer than we / some of us fear.Tim

It appears the Infinity Mask setting is enabled by default anymore. The Acceleration addon just picked up my quad's extra 3 cores and put 'em to work . . . and work they do. Those guys are All at 100% most of the time. I'm thinking that three extra Core2 CPUs at 3.6Ghz couldn't hurt.
